General Surgery · Wound healing: skin graft take

Sample item

In the first 48 hours after application, how does a split-thickness skin graft survive?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Plasmatic imbibition from the wound bed

A graft survives initially by plasmatic imbibition, absorbing nutrients from the serum of the wound bed, and from about day two to three inosculation and capillary ingrowth establish a blood supply. Haematoma, seroma, infection and shear prevent take. Immobilisation and a well-vascularised bed are required.

Option by option

  • A. Plasmatic imbibition from the wound bed (correct)

    Correct. Imbibition sustains the graft early.

  • B. Inosculation with recipient vessels

    Inosculation begins after about 48 hours.

  • C. Direct arterial anastomosis

    Arteries are not anastomosed.

  • D. Lymphatic flow only

    Lymphatics are not the nutritional route.
